Based on countless Qur'anic verses and oral traditions attributed to Muhammad, Islam's learned officials, sheikhs, muftis, and imams throughout the ages have all reached consensus—binding on the entire Muslim community—that Islam is to be at perpetual war with the non-Muslim world until the former subsumes the latter.

Although Islam and Christianity seem to have certain points of doctrine in common, there is an enormous difference between them, not only in beliefs about salvation and Christ but in many other areas affecting daily life, human behavior and attitudes.

Jesus and Muhammad could hardly have been more different in how they lived or in what they taught others. Why should we not expect starkly contrasting legacies - from the conduct of their closest companions to the livability of modern-day countries influenced by the predominance of one founder's teachings over the other?

The Quran contains at least 109 verses that call Muslims to war with nonbelievers for the sake of Islamic rule. Unlike nearly all of the Old Testament verses of violence, the verses of violence in the Quran are mostly open-ended, meaning that they are not restrained by the historical context of the surrounding text. They are part of the eternal, unchanging word of Allah, and just as relevant or subjective as anything else in the Quran.
